Searching for Exotic States with b and c Quarks in D0 Experiment
- 3 Downloads
The latest results of searching for exotic multiquark states with heavy quarks obtained in the D0 experiment (Fermi National Accelerator Laboratory, USA) are presented. In particular, the evidence of existence of a possible four-quark state X(5568) → B s 0 π±in the cases with hadronic and semileptonic decay channels of B s 0 meson is considered, as well as the results of searching for the five-quark states in the J/ψΛ system.
